I was talking on the phone in my trailer, and I looked in the mirror and I saw the badge clipped to my belt, a gun with a holster, and the suit and the tie with the jacket off, and it was just deja vu. I remember that image so clearly from growing up. My dad would come home for lunch, take off his jacket, have the gun and the badge.

The single most important thing in learning my craft was being on the stage.

That's probably fair to say that there is a certain amount of pressure to deliver your next role when you do have a fan base as potent as the 'Battlestar Galactica' family. There was certainly a lot of curiosity to all of us on that show - what are you going to do next? Where can we see you next? That was a question we got more often than not.

For me, a career highlight was being on 'Battlestar Galactica.' Roles like that don't come along very often.

Now, learning how to make a movie is something you can figure out in about an afternoon. The physics of it, the marks, the lights, etc. What's hard to do is to suspend your own feelings of self consciousness. The natural actors can do that; they can become part of a characterization and learn how to maintain it.

I work out every morning for an hour while in front of the news channel or business channels, then I'll ride for four, five hours a day. So I'm on the move all the time, and I think that's the key. A body in motion tends to stay in motion. That's the law of physics.

Great wealth could make an enormous difference over the next decade if they sensibly support the scientific elite. Just the elite. Because the elite makes most of the progress. You should worry about people who produce really novel inventions, not pedantic hacks.

My father was on the faculty in the Chemistry Department of Harvard University; my mother had one year of graduate work in physics before her marriage.
